Filed: 1984-09-10
Abstract: PURPOSE:To obtain optional soft effect and eliminate focus variation even when a soft function is displayed by varying the outward shape of a transparent optical element made of what is called an elastic body capable of deforming reversibly. CONSTITUTION:The variable aberration lens 3 is arranged nearby a stop 4 so that on-axis luminous flux and off-axis luminous flux are given soft effect uniformly. A frame 6 has an annular control plate to deform the optical element 7, and the variable aberration lens enters a normal photographic state having no soft function only when the optical element 7 merely operates as a parallel plane plate. Further, the frame 6 is moved by an operating member to press the outer peripheral part of the optical element 7, and consequently the outward shape of the optical element is deformed, so that the variable aberration lens enters a soft photographic state having the soft function. At this time, the variable aberration lens increases in spherical aberration of high degree to provide an image with excellent soft effect.
